I’m doing a
small fiberglass project and am having trouble making straight end cuts
on the plain-weave cloth. Before I waste any more cloth, do you have any
tips on how to do this?D.V., via e-mailFirst locate
a single fiberglass strand that runs all the way across the fabric. If
you can’t get a grip on the strand, cut a two- to three-inch slit
into the edge of the fabric in order to expose more of the strand. Pull
it out while holding down the opposite end of the fabric. Once you’ve
removed this single strand, you’ll see a clear path to follow with
your scissor or wheel cutter, both of which should be sharp.

I’ve noticed
an occasional “flat spot” or hesitation upon acceleration from
my tender’s two-stroke outboard. What could be wrong?V.P.,
via e-mailMost likely
the problem is a restricted main carburetor jet, although it could be
water in the fuel or an excessively lean fuel mixture. Another possibility
is a faulty accelerator pump, if your tender’s engine is so equipped.
Replacing a carburetor jet or accelerator pump is work for a trained mechanic.

A small amount of
gasoline was mistakenly put into my freshwater tank. None got through
the system, and I emptied the tank. While I use this tank primarily for
cleaning dishes and showering, there is a residual smell. How can I eliminate
it?B.C., via e-mail

Unfortunately you’ll
probably have to remove the tank from your boat. After doing so, seal
its drain end, pour two gallons of undiluted rubbing alcohol along with
a small amount of water into it, and swish it around. The alcohol will
combine with the water as well as the residual hydrocarbons. When you
pour out the solution—in the proper fashion—most of the gasoline
will go with it. Repeat the procedure, then rinse the tank with clean
water from a hose at full pressure, letting the water overflow for a few
minutes.

Next, empty the tank
and pour in the contents of a small box of baking soda. With the hose
on full pressure, fill the tank until it’s half full, then reduce
the pressure and fill the tank all the way. Let the mixture sit for a
few minutes, empty it, and repeat the entire process. After this, you
should not be able to detect any odor.
